IMHO, even if it were possible to do that in .strings file, that would not be a good idea. REASON: It adds the risk that one of the translated versions would accidentally garble that formatting. Strings files are, and should be, purely pairs of strings: key string + value in a given language.

Cancel my previous comment. I see a situation where different grammar (word order) of different languages makes it challenging to adapt correctly without having a placeholder [in my case, a person's name] that can be moved to a different location in the sentence, per language. Without that, have to manually instruct the person translating what the complete sentence is, then give keys to the two parts of the sentence (before and after the placeholder). The translator has to provide a translation for the sentence as a whole, and then break it into the before and after pieces - even though the translation of each piece is not what it would be by itself (one word moved from after to before). Rather than rely on translator to do that correctly, provided a sentence with an example name, let them translate, then had the coder break the sentence down. So it is a more cumbersome process - can't just hand the strings file to translator, then double-check the result to make sure the key-value formatting hasn't been messed up. Extra manual step per language.
